BF Charge Reduction with Gases of Different H2 Ratio in High Temperature Zone

Abstract:

Article Preview

The reduction of different basicity BF charge with gases of different H2 ratio has been determined to simulate different BF technology. The results reveal: reduction rate (R & r) and metallization rate of charge increase with the H2 ratio increasing, and the temperature increasing while the reducing time becomes longer simultaneously. The direct reduction degree of charge in Hydrogen-enrichment BF is very low, thus the energy consumption of Ironmaking could be reduced. There is certain difference between metallization rate and reduction degree due to reduction kinetics. The mass loss rate of coke increases sharply with the H2 ratio increasing, the H2 ratio of gas should be selected an appropriate value.
